Benjamin Peterson5da7e7c2010-03-06 22:44:07 +000023
24Core and Builtins
25-----------------
26
Philip Jenveyaebbaeb2010-04-06 23:24:45 +000027- Issue #7301: Add environment variable $PYTHONWARNINGS.
28
Benjamin Peterson3a1dfa22010-04-06 21:50:00 +000029- Issue #8329: Don't return the same lists from select.select when no fds are
30 changed.
31
Mark Dickinson82791672010-04-06 16:47:55 +000032- Issue #8259: 1L << (2**31) no longer produces an 'outrageous shift error'
33 on 64-bit machines. The shift count for either left or right shift is
34 permitted to be up to sys.maxsize.
35
Benjamin Peterson4ceeeb02010-04-03 22:48:51 +000036- Ensure that tokenization of identifiers is not affected by locale.
37
Tarek Ziadé00002952010-04-03 08:37:59 +000038- Issue #1222585: Added LDCXXSHARED for C++ support. Patch by Arfrever.
39
Benjamin Peterson1c7c11e2010-04-03 01:28:57 +000040- Raise a TypeError when trying to delete a T_STRING_INPLACE struct member.
41
Eric Smithd44b2fc2010-04-02 12:30:56 +000042- Issue #7994: Issue a PendingDeprecationWarning if object.__format__
43 is called with a non-empty format string. This is an effort to
44 future-proof user code. If a derived class does not currently
45 implement __format__ but later adds its own __format__, it would
46 most likely break user code that had supplied a format string. This
47 will be changed to a DeprecationWaring in Python 3.3 and it will be
48 an error in Python 3.4.
49
Antoine Pitroua57df2c2010-03-31 21:32:15 +000050- Issue #8268: Old-style classes (not just instances) now support weak
51 references.
52
Victor Stinner6cbf90f2010-03-25 00:21:53 +000053- Issue #8211: Save/restore CFLAGS around AC_PROG_CC in configure.in, compiler
54 optimizations are disabled when --with-pydebug is used.
55
Victor Stinnerc7790ed2010-03-22 12:36:28 +000056- Issue #1583863: An unicode subclass can now override the __unicode__ method
Victor Stinner95affc42010-03-22 12:24:37 +000057
Benjamin Peterson96545892010-03-21 20:21:00 +000058- Issue #6474: Make error message from passing an inadequate number of keyword
59 arguments to a function correct.
60

Georg Brandlba83f822010-03-14 09:50:54 +000064 (SIGINT). If an error occurs while importing the site module, the error is
65 printed and Python exits. Initialize the GIL before importing the site
Victor Stinner66644262010-03-10 22:30:19 +000066 module.
67
Collin Winter001a3952010-03-18 21:54:01 +000068- Code objects now support weak references.

78
Antoine Pitrouf9de5342010-04-05 21:35:07 +000079- Issue #8321: Give access to OpenSSL version numbers from the `ssl` module,
80 using the new attributes `ssl.OPENSSL_VERSION`, `ssl.OPENSSL_VERSION_INFO`

Mark Dickinson8a950712010-04-03 15:47:46 +000085- Issue #8257: The Decimal construct now accepts a float instance
86 directly, converting that float to a Decimal of equal value:
87

90
Raymond Hettinger34c35b22010-04-03 10:22:00 +000091- collections.Counter() now supports a subtract() method.
92
Raymond Hettingera551f312010-04-04 18:34:45 +000093- the functools module now has a total_ordering() class decorator
Andrew M. Kuchling884d0a32010-04-11 12:48:08 +000094 to simplify the specifyication of rich comparisons.
Raymond Hettingera551f312010-04-04 18:34:45 +000095
Raymond Hettingerbb006cf2010-04-04 21:45:01 +000096- The functools module also adds cmp_to_key() as a tool to transition
Raymond Hettingera551f312010-04-04 18:34:45 +000097 old-style comparison functions to new-style key-functions.
98
Mark Dickinson7c63eee2010-04-02 22:27:36 +000099- Issue #8294: The Fraction constructor now accepts Decimal and float
100 instances directly.
101
Mark Dickinsone096e822010-04-02 10:17:07 +0000102- Issue #7279: Comparisons involving a Decimal signaling NaN now
103 signal InvalidOperation instead of returning False. (Comparisons
Mark Dickinsonf3eeca12010-04-02 10:35:12 +0000104 involving a quiet NaN are unchanged.) Also, Decimal quiet NaNs
105 are now hashable; Decimal signaling NaNs remain unhashable.
Mark Dickinsone096e822010-04-02 10:17:07 +0000106
Mark Dickinson99d80962010-04-02 08:53:22 +0000107- Issue #2531: Comparison operations between floats and Decimal
108 instances now return a result based on the numeric values of the
109 operands; previously they returned an arbitrary result based on
110 the relative ordering of id(float) and id(Decimal).
111
Barry Warsawf7f2d6f2010-03-31 21:07:16 +0000112- Issue #8233: When run as a script, py_compile.py optionally takes a single
113 argument `-` which tells it to read files to compile from stdin. Each line
114 is read on demand and the named file is compiled immediately. (Original
115 patch by Piotr Ożarowski).
116
117- Issue #3135: Add inspect.getcallargs, which binds arguments to a function
118 like a normal call.
Benjamin Peterson7e213252010-03-30 17:58:13 +0000119
Florent Xicluna58b65662010-03-30 16:29:03 +0000120- Backwards incompatible change: Unicode codepoints line tabulation (0x0B) and
121 form feed (0x0C) are now considered linebreaks, as specified in Unicode
122 Standard Annex #14. See issue #7643.

124
Mark Dickinson9588d992010-03-27 11:14:37 +0000125- Comparisons using one of <, <=, >, >= between a complex instance and
126 a Fractions instance now raise TypeError instead of returning
127 True/False. This makes Fraction <=> complex comparisons consistent with
128 int <=> complex, float <=> complex, and complex <=> complex comparisons.
129
Michael Foorde6410c52010-03-29 20:04:23 +0000130- Addition of ``WeakSet`` to the ``weakref`` module.
131

133
Florent Xicluna176cda12010-03-22 22:52:11 +0000134- Issue #8205: Remove the "Modules" directory from sys.path when Python is
135 running from the build directory (POSIX only).

141 now silenced.
142
Florent Xicluna9e7a4c92010-03-22 16:07:38 +0000143- Issue #7703: ctypes supports both buffer() and memoryview(). The former is

148
Vinay Sajip804899b2010-03-22 15:29:01 +0000149- logging: Added getChild utility method to Logger and added isEnabledFor
150 method to LoggerAdapter.
151
Vinay Sajip31e928e2010-03-22 13:02:28 +0000152- Issue #8201: logging: Handle situation of non-ASCII and Unicode
153 logger names existing at the same time, causing a Unicode error
154 when configuration code attempted to sort the existing loggers.

160 Also, enable the SSL_MODE_AUTO_RETRY flag on SSL sockets, so that blocking
161 reads and writes are always retried by OpenSSL itself.
Antoine Pitrou448da712010-03-21 19:33:38 +0000162
Florent Xiclunacf82fa62010-03-21 12:27:20 +0000163- Issue #8179: Fix macpath.realpath() on a non-existing path.

178
Georg Brandlba83f822010-03-14 09:50:54 +0000179- Issue #7774: Set sys.executable to an empty string if ``argv[0]`` has been
Victor Stinner75227342010-03-12 14:30:26 +0000180 set to an non existent program name and Python is unable to retrieve the real
Georg Brandlba83f822010-03-14 09:50:54 +0000181 program name.
Victor Stinner75227342010-03-12 14:30:26 +0000182
Vinay Sajipecfa08f2010-03-12 09:16:10 +0000183- Issue #8117: logging: Improved algorithm for computing initial rollover time
Georg Brandlba83f822010-03-14 09:50:54 +0000184 for ``TimedRotatingFileHandler`` by using the modification time of an
185 existing log file to compute the next rollover time. If the log file does
186 not exist, the current time is used as the basis for the computation.
Vinay Sajip9098ee42010-03-12 06:01:21 +0000187
Georg Brandlba83f822010-03-14 09:50:54 +0000188- Issue #6472: The ``xml.etree`` package is updated to ElementTree 1.3. The

Florent Xicluna47627d52010-03-08 15:20:28 +0000194 classes.
195
Georg Brandlba83f822010-03-14 09:50:54 +0000196- Issue #7143: email: ``get_payload()`` used to strip any trailing newline from
197 a base64 transfer-encoded payload *after* decoding it; it no longer does.
198 This is a behavior change, so email's minor version number is now bumped, to
199 version 4.0.2, for the 2.7 release.

Matthias Klose817acef2010-03-15 00:02:36 +0000223- Issue #8142: Update libffi to the 3.0.9 release.
224
Mark Dickinson4846a8e2010-04-03 14:05:10 +0000225- Issue #8300: When passing a non-integer argument to struct.pack with any
226 integer format code, struct.pack first attempts to convert the non-integer
227 using its __index__ method. If that method is non-existent or raises
228 TypeError it goes on to try the __int__ method, as described below.
229
Georg Brandlba83f822010-03-14 09:50:54 +0000230- Issue #1530559: When passing a non-integer argument to struct.pack with *any*
231 integer format code (one of 'bBhHiIlLqQ'), struct.pack attempts to use the
232 argument's __int__ method to convert to an integer before packing. It also
233 produces a DeprecationWarning in this case. (In Python 2.6, the behaviour
234 was inconsistent: __int__ was used for some integer codes but not for others,
235 and the set of integer codes for which it was used differed between native
236 packing and standard packing.)

Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000524- Issue #6939: Fix file I/O objects in the `io` module to keep the original
Georg Brandlba83f822010-03-14 09:50:54 +0000525 file position when calling `truncate()`. It would previously change the file
526 position to the given argument, which goes against the tradition of
Antoine Pitrouf3fa0742010-01-31 22:26:04 +0000527 ftruncate() and other truncation APIs. Patch by Pascal Chambon.

Georg Brandlba83f822010-03-14 09:50:54 +0000531- Issue #7610: Reworked implementation of the internal ``zipfile.ZipExtFile``
532 class used to represent files stored inside an archive. The new
533 implementation is significantly faster and can be wrapped in a
534 ``io.BufferedReader`` object for more speedups. It also solves an issue
535 where interleaved calls to ``read()`` and ``readline()`` give wrong results.

625
Georg Brandlba83f822010-03-14 09:50:54 +0000626- The ``__complex__()`` method is now looked up on the class of instances to
627 make it consistent with other special methods.

630 `rindex`, `rsplit` and `rpartition` methods. Patch by Florent Xicluna.
631
Mark Dickinson1b34d252010-01-01 17:27:30 +0000632- Issue #5080: A number of functions and methods previously produced a
Georg Brandlba83f822010-03-14 09:50:54 +0000633 DeprecationWarning when passed a float argument where an integer was expected.
634 These functions and methods now raise TypeError instead. The majority of the
635 effects of this change are in the extension modules, but some core functions
636 and methods are affected: notably the 'chr', 'range' and 'xrange' builtins,
637 and many unicode/str methods.

652 least on IEEE 754 platforms), and in particular does not depend on the
653 internal representation of a long.

Georg Brandlba83f822010-03-14 09:50:54 +0000802- Issue #3382: 'F' formatting for float and complex now convert the result to
803 upper case. This only affects 'inf' and 'nan', since 'f' no longer converts
804 to 'g' for large values.
Amaury Forgeot d'Arcd7288712009-12-01 21:51:04 +0000805
Georg Brandlba83f822010-03-14 09:50:54 +0000806- Remove switch from "%f" formatting to "%g" formatting for floats larger than
807 1e50 in absolute value.
Mark Dickinson9dd5e162009-11-23 20:54:09 +0000808
Georg Brandlba83f822010-03-14 09:50:54 +0000809- Remove restrictions on precision when formatting floats. E.g., "%.120g" %
810 1e-100 used to raise OverflowError, but now gives the requested 120
811 significant digits instead.

818 10.6.
Ronald Oussoren315cd0c2009-11-19 16:25:21 +0000819
Georg Brandlba83f822010-03-14 09:50:54 +0000820- Issue #7117: ``repr(x)`` for a float x returns a result based on the shortest
821 decimal string that's guaranteed to round back to x under correct rounding
822 (with round-half-to-even rounding mode). Previously it gave a string based on
823 rounding x to 17 decimal digits. repr(x) for a complex number behaves
824 similarly. On platforms where the correctly-rounded strtod and dtoa code is
825 not supported (see below), repr is unchanged.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000826
Georg Brandlba83f822010-03-14 09:50:54 +0000827- Issue #7117: On almost all platforms: float-to-string and string-to-float
828 conversions within Python are now correctly rounded. Places these conversions
829 occur include: str for floats and complex numbers; the float and complex
830 constructors; old-style and new-style numeric formatting; serialization and
831 deserialization of floats and complex numbers using marshal, pickle and json;
832 parsing of float and imaginary literals in Python code; Decimal-to-float
833 conversion.
Mark Dickinsonb678de82009-11-19 18:41:49 +0000834
Georg Brandlba83f822010-03-14 09:50:54 +0000835 The conversions use a Python-adapted version of David Gay's well-known dtoa.c,
836 providing correctly-rounded strtod and dtoa C functions. This code is
837 supported on Windows, and on Unix-like platforms using gcc, icc or suncc as
838 the C compiler. There may be a small number of platforms on which correct
839 operation of this code cannot be guaranteed, so the code is not used: notably,
840 this applies to platforms where the C double format is not IEEE 754 binary64,
841 and to platforms on x86 hardware where the x87 FPU is set to 64-bit precision
842 and Python's configure script is unable to determine how to change the FPU
843 precision. On these platforms conversions use the platform strtod and dtoa,
844 as before.

Georg Brandlba83f822010-03-14 09:50:54 +0000846- Issue #7117: Backport round implementation from Python 3.x. ``round()`` now
847 uses the correctly-rounded string <-> float conversions described above (when
848 available), and so produces correctly rounded results that will display nicely
849 under the float repr. There are two related small changes: (1) round now
850 accepts any class with an ``__index__()`` method for its second argument (but
851 no longer accepts floats for the second argument), and (2) an excessively
852 large second integer argument (e.g., ``round(1.234, 10**100)``) no longer
853 raises an exception.

Antoine Pitrouf8387af2009-03-23 18:41:45 +00001070- Issue #4688: Add a heuristic so that tuples and dicts containing only
Georg Brandlba83f822010-03-14 09:50:54 +00001071 untrackable objects are not tracked by the garbage collector. This can reduce
1072 the size of collections and therefore the garbage collection overhead on
1073 long-running programs, depending on their particular use of datatypes.

1080 internal representation of integers, for performance reasons. Base 2**30 is
1081 enabled by default on 64-bit machines. Add --enable-big-digits option to
1082 configure, which overrides the default. Add sys.long_info structseq to
1083 provide information about the internal format.

Brett Cannon6c4cff02009-03-11 04:51:06 +00001096 requirement. Means the DeprecationWarning from Python 2.6 can go away.
1097
Georg Brandlba83f822010-03-14 09:50:54 +00001098- Issue #5247: Improve error message when unknown format codes are used when
1099 using ``str.format()`` with str, unicode, long, int, and float arguments.
Eric Smithe9fb6862009-02-20 14:02:36 +00001100
Georg Brandlba83f822010-03-14 09:50:54 +00001101- Running Python with the -3 option now also warns about classic division for

Benjamin Petersone18ef192009-01-20 14:21:16 +00001113- Issue #4978: Passing keyword arguments as unicode strings is now allowed.
1114
Georg Brandl29c6a282009-04-05 20:23:13 +00001115- Issue #1242657: the __len__() and __length_hint__() calls in several tools
Raymond Hettingerb5163702009-02-02 21:50:13 +00001116 were suppressing all exceptions. These include list(), filter(), map(),
1117 zip(), and bytearray().
1118
Benjamin Peterson596d3062009-01-19 15:42:23 +00001119- os.ftruncate raises OSErrors instead of IOErrors for consistency with other os

Georg Brandlba83f822010-03-14 09:50:54 +00001127- Issue #4935: The overflow checking code in the expandtabs() method common to
1128 str, bytes and bytearray could be optimized away by the compiler, letting the

Georg Brandlba83f822010-03-14 09:50:54 +00001146- Issue #1180193: When importing a module from a .pyc (or .pyo) file with an
1147 existing .py counterpart, override the co_filename attributes of all code
1148 objects if the original filename is obsolete (which can happen if the file has
1149 been renamed, moved, or if it is accessed through different paths). Patch by

1203
Georg Brandlba83f822010-03-14 09:50:54 +00001204- Issue #4233: Changed semantic of ``_fileio.FileIO``'s ``close()`` method on
1205 file objects with closefd=False. The file descriptor is still kept open but
1206 the file object behaves like a closed file. The ``FileIO`` object also got a

1232 this code path is really executed because I cannot move to such directory on
1233 win2k)

2633
Martin v. Löwis9fa5a282008-09-11 06:53:30 +00002634- Issue #3642: Suppress warning in obmalloc when size_t is larger than uint.
2635
Amaury Forgeot d'Arc05e34492008-09-10 22:04:45 +00002636- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
2637 PyString_FromFormat or PyErr_Format to display size_t values. The macro
2638 PY_FORMAT_SIZE_T is designed to select the correct format for the OS
2639 ``printf`` function, whereas PyString_FromFormat has an independent
2640 implementation and uses "%zd" on all platforms for size_t values.
2641 This makes a difference on win64, where ``printf`` needs "%Id" to display
2642 64bit values.
2643
Benjamin Peterson97179b02008-09-09 20:55:01 +00002644- Issue #3634: _weakref.ref(Exception).__init__() gave invalid return value on
2645 error.
2646
Amaury Forgeot d'Arcd3ffb892008-09-09 07:24:30 +00002647- Issue #3777: long() applied to a float object now always return a long
2648 object; previously an int would be returned for small values. the __long__
2649 method is allowed to return either an int or a long, but the behaviour of
2650 float objects should not change to respect backward compatibility.
2651
Amaury Forgeot d'Arc3571fbf2008-09-01 19:52:00 +00002652- Issue #3751: str.rpartition would perform a left-partition when called with
2653 a unicode argument.
2654
Benjamin Peterson17f03ca2008-09-01 14:18:30 +00002655- Issue #3683: Fix compilation when --without-threads is given.
2656
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002657- Issue #3668: Fix a memory leak with the "s*" argument parser in
Vinay Sajip35e3b032008-09-01 14:33:59 +00002658 PyArg_ParseTuple and friends, which occurred when the argument for "s*"
Antoine Pitroud4ae97b2008-08-29 18:39:48 +00002659 was correctly parsed but parsing of subsequent arguments failed.
2660
Vinay Sajip35e3b032008-09-01 14:33:59 +00002661- Issue #2534: speed up isinstance() and issubclass() by 50-70%, so as to
Antoine Pitrou0668c622008-08-26 22:42:08 +00002662 match Python 2.5 speed despite the __instancecheck__ / __subclasscheck__
2663 mechanism. In the process, fix a bug where isinstance() and issubclass(),
2664 when given a tuple of classes as second argument, were looking up
2665 __instancecheck__ / __subclasscheck__ on the tuple rather than on each
2666 type object.
2667
Neal Norwitz18aa3882008-08-24 05:04:52 +00002668- Fix crashes on memory allocation failure found with failmalloc.
2669
2670- Fix memory leaks found with valgrind and update suppressions file.
2671
2672- Fix compiler warnings in opt mode which would lead to invalid memory reads.
2673
2674- Fix problem using wrong name in decimal module reported by pychecker.
2675
Christian Heimes7d4c3172008-08-22 19:47:25 +00002676- Silenced another compiler warning about a used but not defined
2677 function 'stringlib_contains_obj'.
2678
Benjamin Peterson712ee922008-08-24 18:10:20 +00002679- Added warnings on the use of ``__getslice__``, ``__setslice__``, or
2680 ``__delslice__``.
2681
Gregory P. Smith2bb25cc2008-09-02 05:29:51 +00002682- Issue #3678: Correctly pass LDFLAGS and LDLAST to the linker on shared
2683 library targets in the Makefile.
2684
Gregory P. Smith980b99b2008-09-07 05:15:18 +00002685- Issue #1204: The configure script now tests for additional libraries
2686 that may be required when linking against readline. This fixes issues
2687 with x86_64 builds on some platforms (a few Linux flavors and OpenBSD).
2688

Amaury Forgeot d'Arc24cb3822008-09-11 20:56:13 +00002697- Issue #3640: Pickling a list or a dict uses less local variables, to reduce
2698 stack usage in the case of deeply nested objects.
2699
Guido van Rossume3c4fd92008-09-10 14:27:00 +00002700- Issue #3629: Fix sre "bytecode" validator for an end case.
2701
Martin v. Löwis24329ba2008-09-10 13:38:12 +00002702- Issue #3811: The Unicode database was updated to 5.1.
2703
Nick Coghland2e09382008-09-11 12:11:06 +00002704- Issue #3781: Further warnings.catch_warnings() cleanup to prevent
2705 silent misbehaviour when a single instance is nested in multiple
2706 with statements, or when the methods are invoked in the wrong order.
2707
Vinay Sajip844f7412008-09-09 13:42:08 +00002708- Issue #3809: Fixed spurious 'test.blah' file left behind by test_logging.
2709
Nick Coghland2e09382008-09-11 12:11:06 +00002710- Issue #3781: Clean up the API for warnings.catch_warnings() by having it
Brett Cannon672237d2008-09-09 00:49:16 +00002711 return a list or None rather than a custom object.
2712
Benjamin Peterson6ac7d7c2008-09-06 19:28:11 +00002713- Issue #1638033: Cookie.Morsel gained the httponly attribute.
2714
Antoine Pitrouebcd0ce2008-09-05 23:30:23 +00002715- Issue #3535: zipfile couldn't read some zip files larger than 2GB.

2720 its symbolic link.
2721
Vinay Sajip65d66e12008-09-04 07:31:21 +00002722- Issue #3772: Fixed regression problem in StreamHandler.emit().

Brett Cannon1eaf0742008-09-02 01:25:16 +00002736- Issue 3602: Moved test.test_support.catch_warning() to
2737 warnings.catch_warnings() along with some API cleanup. Expanding the tests
2738 for catch_warnings() also led to an improvement in the raising of a
2739 DeprecationWarning related to warnings.warn_explicit().
2740
Benjamin Peterson973e6c22008-09-01 23:12:58 +00002741- The deprecation warnings for the old camelCase threading API were removed.

2744
Christian Heimesa27a62e2008-08-22 19:55:54 +00002745- Silenced a trivial compiler warning in the sqlite module.
2746
Christian Heimes1cc69632008-08-22 20:10:27 +00002747- Fixed two format strings in the _collections module.
2748

2750 directory.
Benjamin Petersonf22c26e2008-09-01 14:13:43 +00002751
Gregory P. Smithd7122032008-09-02 05:36:11 +00002752- Issue #3708: os.urandom no longer goes into an infinite loop when passed a
2753 non-integer floating point number.
2754
Vinay Sajip65d66e12008-09-04 07:31:21 +00002755- Issue #3110: multiprocessing fails to compiel on solaris 10 due to missing

2762 _check_logger_class from multiprocessing.
2763
Amaury Forgeot d'Arc293924b2008-09-02 23:19:56 +00002764- Issue #2975: When compiling several extension modules with Visual Studio 2008
2765 from the same python interpreter, some environment variables would grow
2766 without limit.
2767
Benjamin Peterson37346b22008-08-23 20:27:43 +00002768- Issue #3643: Added a few more checks to _testcapi to prevent segfaults by
2769 exploitation of poor argument checking.
2770
Gerhard Häringef2276b2008-09-12 13:54:06 +00002771- sqlite3: Changed docstring of iterdump() to mark method as "Non-standard".
2772
Gerhard Häring6e1afcf2008-09-12 18:58:57 +00002773- Issue #3103: Reduced globals symbols used by sqlite3 module and made sure all
2774 remaining ones have "pysqlite_" prefix.
2775
Gerhard Häringe6872eb2008-09-12 22:33:22 +00002776- Issue #3846: Release the GIL during sqlite3_prepare calls. This improves

Nick Coghland2e09382008-09-11 12:11:06 +00002783- Issue #3781: Add test.test_support.check_warnings() as a convenience
2784 wrapper for warnings.catch_warnings() that makes it easier to check
2785 that expected warning messages are being reported.
2786
Amaury Forgeot d'Arcfeb8cad2008-09-06 20:53:51 +00002787- Issue #3796: Some tests functions were not enabled in test_float.

Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002805What's New in Python 2.6 beta 3?
2806================================
2807
Barry Warsaw07a4a382008-08-21 01:15:08 +00002808*Release date: 20-Aug-2008*
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00002809
2810Core and Builtins
2811-----------------
2812
Guido van Rossumf8402962008-08-20 15:01:50 +00002813- Issue #1878: Remove Py_TPFLAGS_HAVE_VERSION_TAG from
2814 Py_TPFLAGS_DEFAULT when not building the core. This means 3rd party
2815 extensions do not automatically benefit from the class attribute
2816 cache; they will have to explicitly add Py_TPFLAGS_HAVE_VERSION_TAG
2817 to their tp_flags field if they care. This is a backwards
2818 compatibility feature; in 3.0, all types will use the cache by
2819 default.
2820
Benjamin Petersonf647dc12008-08-20 01:27:30 +00002821- Keyword arguments can now follow starred arguments. (``f(a, *args,
2822 keyword=23)`` is now valid syntax.)
2823
Thomas Heller0ad5ae02008-08-19 19:25:04 +00002824- ctypes function pointers that are COM methods have a boolean True
2825 value again.
2826
Martin v. Löwisf91d46a2008-08-12 14:49:50 +00002827- Issue #3139: Make buffer-interface thread-safe wrt. PyArg_ParseTuple,
2828 by denying s# to parse objects that have a releasebuffer procedure,
2829 and introducing s*.
2830
Georg Brandl1e13ea92008-08-11 09:07:59 +00002831- Issue #3537: Fix an assertion failure when an empty but presized dict
2832 object was stored in the freelist.
2833
Mark Dickinsonb6467572008-08-04 21:30:09 +00002834- Issue #1481296: Make long(float('nan')) and int(float('nan')) raise
2835 ValueError consistently across platforms.
2836
Amaury Forgeot d'Arc39fd6722008-07-31 21:28:03 +00002837- Issue #3479: On platforms where sizeof(int) is smaller than sizeof(long)
2838 (64bit Unix, for example), unichr() would truncate its argument and return
2839 u'\x00' for unichr(2**32). Now it properly raises an OverflowError.
2840
Neal Norwitze7d8be82008-07-31 17:17:14 +00002841- Apply security patches from Apple.
2842
Amaury Forgeot d'Arc246daed2008-07-31 00:42:16 +00002843- Issue #2542: Now that issubclass() may call arbitrary code, ensure that
2844 PyErr_ExceptionMatches returns 0 when an exception occurs there.
2845
Antoine Pitrou92f82162008-07-25 22:22:08 +00002846- Issue #1819: function calls with several named parameters are now on
2847 average 35% faster (as measured by pybench).
2848
Amaury Forgeot d'Arce4921fe2008-07-21 22:00:38 +00002849- Issue #2378: An unexpected UnboundLocalError or NameError could appear when
2850 the python debugger steps into a class statement: the free variables (local
2851 variables defined in an outer scope) would be deleted from the outer scope.
2852
Gregory P. Smith0470bab2008-07-22 04:46:32 +00002853- Issue #2620: Overflow checking when allocating or reallocating memory
2854 was not always being done properly in some python types and extension
2855 modules. PyMem_MALLOC, PyMem_REALLOC, PyMem_NEW and PyMem_RESIZE have
2856 all been updated to perform better checks and places in the code that
2857 would previously leak memory on the error path when such an allocation
2858 failed have been fixed.

2861-------
2862
Hirokazu Yamamoto838c79f2008-08-20 13:14:07 +00002863- Issue #3612: Added some missing basic types in ctypes.wintypes.
2864
Benjamin Petersone977ad42008-08-20 01:42:01 +00002865- The methods ``is_in_tuple()``, ``is_vararg()``, and ``is_keywordarg()`` of
2866 symtable.Symbol have been deprecated for removal in 3.0 and the next release.
2867
Amaury Forgeot d'Arc351ffb82008-08-18 19:23:47 +00002868- Issue #2234: distutils failed for some versions of the cygwin compiler. The
2869 version reported by these tools does not necessarily follow the python
2870 version numbering scheme, so the module is less strict when parsing it.
2871
Nick Coghlanf70385a2008-08-18 12:42:46 +00002872- Issue #2235: Added Py3k warnings for types which will become unhashable
2873 under the stricter __hash__ inheritance rules in 3.0. Several types
2874 which did not meet the rules for hash invariants and were already
2875 unhashable in 3.0 have now been explicitly flagged as unhashable in
2876 2.6 as well (collections.Mapping, collections.Set, unittest.TestSuite,
2877 xml.dom.minidom.NamedNodeMap, numbers.Number, UserList.UserList)
2878
Brett Cannon88f801d2008-08-18 00:46:22 +00002879- Update __all__ for cookielib, csv, os, urllib2, and weakref to include things
2880 imported into the module but exposed as part of the module's API.
2881
Brett Cannon7b96f072008-08-18 00:41:11 +00002882- Remove an unneeded import of abc.ABCMeta from 'inspect'.
2883
Brett Cannon46225e72008-08-18 00:36:52 +00002884- Remove unneeded imports of 'sys' and 'warnings' from 'io'.

Brett Cannon25c9d6a2008-08-17 22:10:11 +00002886- Remove unneeded imports of 'warnings' from shelve, filecmp, and dummy_thread.
2887
Hirokazu Yamamoto41a81eb2008-08-17 13:10:46 +00002888- Issue #3575: Incremental decoder's decode function now takes bytearray
2889 by using 's*' instead of 't#'.
2890
Mark Dickinson3e4caeb2009-02-21 20:27:01 +00002891- Issue #2222: Fixed reference leak when occurred os.rename()
Hirokazu Yamamoto7f30a682008-08-17 09:46:56 +00002892 fails unicode conversion on 2nd parameter. (windows only)
2893
Facundo Batista94f243a2008-08-17 03:38:39 +00002894- Issue 2464. urllib2 now supports a malformation in the URL received
2895 in a redirect.
2896
Brett Cannonabe423e2008-08-16 21:47:07 +00002897- Silence the DeprecationWarning raised when importing mimetools in
Brett Cannon721b1452008-08-16 22:00:27 +00002898 BaseHTTPServer, cgi (and rfc822), httplib.
Brett Cannonabe423e2008-08-16 21:47:07 +00002899
Facundo Batistaeb90b782008-08-16 14:44:07 +00002900- Issue #2776: fixed small issue when handling an URL with double slash
2901 after a 302 response in the case of not going through a proxy.
2902
Antoine Pitroub90a8be2008-08-15 21:03:21 +00002903- Issue #2676: in the email package, content-type parsing was hanging on
2904 pathological input because of quadratic or exponential behaviour of a
2905 regular expression.
2906
Antoine Pitrou11ec65d2008-08-14 21:04:30 +00002907- Issue #3476: binary buffered reading through the new "io" library is now
2908 thread-safe.
2909
Brett Cannonbf3157b2008-08-14 05:00:03 +00002910- Silence the DeprecationWarning of rfc822 when it is imported by mimetools
2911 since mimetools itself is deprecated. Because modules are cached, all
2912 subsequent imports of rfc822 will not raise a visible DeprecationWarning.
2913
Antoine Pitrou9fcd4b32008-08-11 17:21:36 +00002914- Issue #3134: shutil referenced undefined WindowsError symbol.
2915
Robert Schuppenies14646332008-08-10 11:01:53 +00002916- Issue #1342811: Fix leak in Tkinter.Menu.delete. Commands associated to
2917 menu entries were not deleted.
2918
Brett Cannon83e81842008-08-09 23:30:55 +00002919- Copied the implementation of reduce() to _functools.reduce() to have a
2920 version that did not raise a DeprecationWarning under -3.
2921
Antoine Pitrou76b8bee2008-08-09 17:27:23 +00002922- Issue #3205: When iterating over a BZ2File fails allocating memory, raise

2945 raised an AttributeError.
2946
Benjamin Peterson01a24322008-07-28 23:35:27 +00002947- Issue #2523: Fix quadratic behaviour when read()ing a binary file without
Antoine Pitroude781a42008-08-09 12:43:23 +00002948 asking for a specific length. This problem only affected files opened
2949 using the new "io" module, not the built-in open() function.

2976 mode 0600 rather than 000 under Unix.
2977
Gregory P. Smitha36f8fe2008-08-04 00:13:29 +00002978- Issue #1857: subprocess.Popen.poll gained an additional _deadstate keyword

3000================================
3001
Amaury Forgeot d'Arc90d07172008-07-21 21:36:24 +00003002*Release date: 17-Jul-2008*

Raymond Hettingere3ae6552008-06-20 04:18:15 +00003004Core and Builtins
3005-----------------
3006
Georg Brandl3e483f62008-07-16 22:57:41 +00003007- Issue #3156: Fix inconsistent behavior of the bytearray type: all
3008 its methods now allow for items objects that can be converted to
3009 an integer using operator.index().
3010
Mark Dickinson64b7e502008-07-16 09:40:03 +00003011- Issue #3360: Fix incorrect parsing of '020000000000.0', which
3012 produced a ValueError instead of giving the correct float.
3013
Eric Smitha5fa5a22008-07-16 00:11:49 +00003014- Issue #3083: Add alternate (#) formatting for bin, oct, hex output
3015 for str.format(). This adds the prefix 0b, 0o, or 0x, respectively.
3016
Mark Dickinson7103aa42008-07-15 19:08:33 +00003017- Issue #3008: the float type has a new instance method 'float.hex'
3018 and a new class method 'float.fromhex' to convert floating-point
3019 numbers to and from hexadecimal strings, respectively.
3020
Nick Coghlan6d6bd442008-07-15 15:40:22 +00003021- Issue #2235: __hash__ is once again inherited by default. To allow
3022 collections.Hashable to remain meaningful in the presence of the
3023 default hash implementation (object.__hash__), it is now possible
3024 to explicit block inheritance of hash by setting __hash__=None at
3025 the Python level, or tp_hash=PyObject_HashNotImplemented at the C
3026 level.
3027
Nick Coghlanb028f502008-07-13 14:52:36 +00003028- Issue #3221: Issue a RuntimeWarning instead of raising SystemError if
3029 the parent module cannot be found while performing an absolute import.
3030 This means that an incorrectly defined __package__ attribute will
3031 now only prevent relative imports in that module rather than causing
3032 all imports from that module to fail.
3033
Nick Coghlan14ff9942008-07-08 14:21:42 +00003034- Issue #2517: Allow unicode messages in Exceptions again by correctly
3035 bypassing the instance dictionary when looking up __unicode__ on
3036 new-style classes.
3037
Amaury Forgeot d'Arcbdd941f2008-07-01 20:38:04 +00003038- Issue #3242: Fix a crash inside the print statement, if sys.stdout is
3039 set to a custom object whose write() method happens to install
3040 another file in sys.stdout.
3041
Amaury Forgeot d'Arc1f40c8a2008-06-30 22:42:40 +00003042- Issue #3088: Corrected a race condition in classes derived from
3043 threading.local: the first member set by a thread could be saved in
3044 another thread's dictionary.
3045
Mark Dickinson1ec2fcd2008-06-20 14:53:43 +00003046- Issue #3004: Minor change to slice.indices(): the start and stop
3047 arguments are now treated identically, making the behaviour easier
3048 to describe and understand. For example, slice(None, -10,
3049 1).indices(9) now returns (0, 0, 1) instead of (0, -1, 1), and
3050 slice(None, 10, -1).indices(10) returns (9, 9, -1) instead of (9,
3051 10, -1).
3052
Georg Brandl278fc502008-07-19 12:46:12 +00003053- Issue #3219: Calling a function with repeated keyword arguments,
3054 f(a=2, a=23), would not cause a syntax error. This was a regression
3055 from 2.4 caused by the switch to the new compiler.
Benjamin Peterson175e4d92008-07-01 19:34:52 +00003056
Georg Brandl278fc502008-07-19 12:46:12 +00003057- Issue #2862: Make int and float freelist management consistent with
3058 other freelists. Changes their CompactFreeList apis into
3059 ClearFreeList apis and calls them via gc.collect().

Thomas Heller57adf222008-08-14 19:10:48 +00003064- Issue #3554: ctypes.string_at and ctypes.wstring_at did call Python
3065 api functions without holding the GIL, which could lead to a fatal
3066 error when they failed.
3067
Martin v. Löwisaabf4042008-08-02 07:20:25 +00003068- Issue #799428: Fix Tkinter.Misc._nametowidget to unwrap Tcl command objects.

Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003093- Issue #839496: SimpleHTTPServer used to open text files in text mode. This is
3094 both unnecessary (HTTP allows text content to be sent in several forms) and
Andrew M. Kuchlingcc3f2b12008-07-10 14:43:31 +00003095 wrong because the actual transmitted size could differ from the
Amaury Forgeot d'Arc0f7cddc2008-07-06 21:34:39 +00003096 content-length. The problem had been corrected in the 2.4 branch, but never
3097 merged into trunk.
3098
Georg Brandle78fbcc2008-07-05 10:13:36 +00003099- Issue #2663: add filtering capability to shutil.copytree().

Nick Coghlanc060b0e2008-07-02 13:09:19 +00003112- Issue #3190: Pydoc now hides the automatic module attribute __package__ (the
3113 handling is now the same as that of other special attributes like __name__).
3114
Brett Cannon8bb8fa52008-07-02 01:57:08 +00003115- Issue #2885 (partial): The urllib.urlopen() function has been deprecated for

3500
Brett Cannonb61d8012008-05-11 23:39:04 +00003501- ``Lib/lib-old`` is now added to sys.path.
3502
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003503- On MacOS X it is now possible to install the framework in 64-bit
3504 mode or even as a 4-way universal binary (that is, PPC, i386,
Georg Brandl5cc774e2008-06-11 20:28:06 +00003505 PPC64 and x86_64 support in one binary).
Ronald Oussoren5640ce22008-06-05 12:58:24 +00003506
3507 This is controlled by the configure argument ``--with-universal-archs``:
3508
3509 - ``--with-universal-archs=all``: install 4-way universal
3510
3511 - ``--with-universal-archs=32-bit``: install 2-way universal, 32-bit (the default)
3512
3513 - ``--with-universal-archs=64-bit``: install 2-way universal, 64-bit
3514
3515 This option should be used in combination with ``--enable-universalsdk=``.
3516
3517 NOTE: 64-bit and 4-way builds are only suppported on Mac OS X 10.5 (or later).

Christian Heimes7a990612008-05-26 13:15:11 +00003526
3527- The PyString functions have been renamed to PyBytes. A batch of
3528 defines were added so that the linker still sees the original
3529 PyString names.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003567- Issue #1631171: Re-implement the 'warnings' module in C (the
3568 original Python code has been kept as backup). This will allow for
3569 using the 'warning's machinery in such places as the parser where
3570 use of pure Python code is not possible. Both the ``showarning()``
3571 and ``formatwarning()`` gain an optional 'line' argument which is
3572 not called by default for backwards-compatibility reasons. Setting
3573 ``warnings.showwarning()`` to an implementation that lacks support
3574 for the ``line`` argument will raise a DeprecationWarning.

Gregory P. Smithd59fefb2008-04-22 08:11:33 +00003599- The getpass module has been improved on Unix. It now uses /dev/tty
3600 by default and uses stderr instead of stdout. A GetPassWarning is
3601 issued when input echo cannot be controlled.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003616- Issue #2513: distutils on Windows is now capable of cross-compiling
Mark Hammond495cf992008-04-07 01:53:39 +00003617 extension modules between 32 and 64 bit platforms. See the distutls

Georg Brandl3ee81df2008-05-17 18:14:43 +00003637- Issue #2550: The approach used by client/server code for obtaining
3638 ports to listen on in network-oriented tests has been refined in an
3639 effort to facilitate running multiple instances of the entire
3640 regression test suite in parallel without issue.
3641 test_support.bind_port() has been fixed such that it will always
3642 return a unique port -- which wasn't always the case with the
3643 previous implementation, especially if socket options had been set
3644 that affected address reuse (i.e. SO_REUSEADDR, SO_REUSEPORT). The
3645 new implementation of bind_port() will actually raise an exception
3646 if it is passed an AF_INET/SOCK_STREAM socket with either the
3647 SO_REUSEADDR or SO_REUSEPORT socket option set. Furthermore, if
3648 available, bind_port() will set the SO_EXCLUSIVEADDRUSE option on
3649 the socket it's been passed. This currently only applies to
3650 Windows. This option prevents any other sockets from binding to the
3651 host/port we've bound to, thus removing the possibility of the
3652 'non-deterministic' behaviour, as Microsoft puts it, that occurs
3653 when a second SOCK_STREAM socket binds and accepts to a host/port
3654 that's already been bound by another socket. The optional preferred
3655 port parameter to bind_port() has been removed. Under no
3656 circumstances should tests be hard coding ports!
3657
3658 test_support.find_unused_port() has also been introduced, which will
3659 pass a temporary socket object to bind_port() in order to obtain an
3660 unused port. The temporary socket object is then closed and
3661 deleted, and the port is returned. This method should only be used
3662 for obtaining an unused port in order to pass to an external program
3663 (i.e. the -accept [port] argument to openssl's s_server mode) or as
3664 a parameter to a server-oriented class that doesn't give you direct
3665 access to the underlying socket used.
3666
3667 Finally, test_support.HOST has been introduced, which should be used
3668 for the host argument of any relevant socket calls (i.e. bind and
3669 connect).
Trent Nelsone41b0062008-04-08 23:47:30 +00003670
3671 The following tests were updated to following the new conventions:
Georg Brandl3ee81df2008-05-17 18:14:43 +00003672 test_socket, test_smtplib, test_asyncore, test_ssl, test_httplib,
Trent Nelsone41b0062008-04-08 23:47:30 +00003673 test_poplib, test_ftplib, test_telnetlib, test_socketserver,
3674 test_asynchat and test_socket_ssl.
3675
Georg Brandl3ee81df2008-05-17 18:14:43 +00003676 It is now possible for multiple instances of the regression test
3677 suite to run in parallel without issue.

3944-----------------
3945
Fred Drakea8ee94b2008-03-01 02:45:07 +00003946- Issue #2051: pyc and pyo files are no longer created with permission
Barry Warsaw52973612008-03-01 02:23:38 +00003947 644. The mode is now inherited from the py file.

3950
3951- Patch #1759: Backport of PEP 3129 class decorators.
Christian Heimes5224d282008-02-23 15:01:05 +00003952
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003953- Issue #1881: An internal parser limit has been increased. Also see
Facundo Batistafc2d0102008-02-23 12:01:13 +00003954 issue 215555 for a discussion.
3955
Eric Smitha73fbe72008-02-23 03:09:44 +00003956- Added the future_builtins module, which contains hex() and oct().
3957 These are the PEP 3127 version of these functions, designed to be
3958 compatible with the hex() and oct() builtins from Python 3.0. They
3959 differ slightly in their output formats from the existing, unchanged
3960 Python 2.6 builtins. The expected usage of the future_builtins
3961 module is:
3962 from future_builtins import hex, oct
3963
Eric Smith7ef40bf2008-02-20 23:34:22 +00003964- Issue #1600: Modifed PyOS_ascii_formatd to use at most 2 digit
3965 exponents for exponents with absolute value < 100. Follows C99
3966 standard. This is a change on Windows, which would use 3 digits.
3967 Also, added 'n' to the formats that PyOS_ascii_formatd understands,
3968 so that any alterations it does to the resulting string will be
3969 available in stringlib/formatter.h (for float.__format__).
3970
Eric Smith5a3c1352008-02-19 13:21:56 +00003971- Implemented PEP 3101, Advanced String Formatting. This adds a new
3972 builtin format(); a format() method for str and unicode; a
3973 __format__() method to object, str, unicode, int, long, float, and
3974 datetime; the class string.Formatter; and the C API
3975 PyObject_Format().
3976
Georg Brandl3ee81df2008-05-17 18:14:43 +00003977- Fixed several potential crashes, all caused by specially crafted
3978 __del__ methods exploiting objects in temporarily inconsistent
3979 state.
Amaury Forgeot d'Arc632fad32008-02-16 20:55:24 +00003980
Vinay Sajipb7edfc42008-04-02 21:10:23 +00003981- Issue #2115: Important speedup in setting __slot__ attributes. Also
Georg Brandl3ee81df2008-05-17 18:14:43 +00003982 prevent a possible crash: an Abstract Base Class would try to access
3983 a slot on a registered virtual subclass.

Georg Brandl3ee81df2008-05-17 18:14:43 +00003988- Clear all free lists during a gc.collect() of the highest generation
3989 in order to allow pymalloc to free more arenas. Python may give back
3990 memory to the OS earlier.
Christian Heimes3b718a72008-02-14 12:47:33 +00003991
Georg Brandl3ee81df2008-05-17 18:14:43 +00003992- Issue #2045: Fix an infinite recursion triggered when printing a
3993 subclass of collections.defaultdict, if its default_factory is set
3994 to a bound method.
Amaury Forgeot d'Arcb01aa432008-02-08 00:56:02 +00003995
Christian Heimesf75dbef2008-02-08 00:11:31 +00003996- Fixed a minor memory leak in dictobject.c. The content of the free
3997 list was not freed on interpreter shutdown.
3998
Georg Brandl21e99f42010-03-07 15:23:59 +00003999- Limit free list of method and built-in function objects to 256
Georg Brandl3ee81df2008-05-17 18:14:43 +00004000 entries each.
Christian Heimes6075a822008-02-06 12:44:34 +00004001
Georg Brandl3ee81df2008-05-17 18:14:43 +00004002- Patch #1953: Added ``sys._compact_freelists()`` and the C API
4003 functions ``PyInt_CompactFreeList`` and ``PyFloat_CompactFreeList``
Christian Heimes422051a2008-02-04 18:00:12 +00004004 to compact the internal free lists of pre-allocted ints and floats.
4005
Georg Brandl3ee81df2008-05-17 18:14:43 +00004006- Issue #1983: Fixed return type of fork(), fork1() and forkpty()
4007 calls. Python expected the return type int but the fork familie
4008 returns pi_t.
Christian Heimes951cc0f2008-01-31 23:08:23 +00004009
Georg Brandl3ee81df2008-05-17 18:14:43 +00004010- Issue #1678380: Fix a bug that identifies 0j and -0j when they
4011 appear in the same code unit.
Mark Dickinson105be772008-01-31 22:17:37 +00004012
Georg Brandl3ee81df2008-05-17 18:14:43 +00004013- Issue #2025: Add tuple.count() and tuple.index() methods to comply
4014 with the collections.Sequence API.
Raymond Hettinger5b07ebc2008-02-07 00:54:20 +00004015
Georg Brandl3ee81df2008-05-17 18:14:43 +00004016- Patch #1970 by Antoine Pitrou: Speedup unicode whitespace and
4017 linebreak detection

Georg Brandl3ee81df2008-05-17 18:14:43 +00004019- Added ``PyType_ClearCache()`` and ``sys._clear_type_cache`` to clear
4020 the internal lookup cache for ref leak tests.
Christian Heimes908caac2008-01-27 23:34:59 +00004021
Georg Brandl3ee81df2008-05-17 18:14:43 +00004022- Patch #1473257: generator objects gain a gi_code attribute. This is
4023 the same object as the func_code attribute of the function that
4024 produced the generator.
Georg Brandl0cdf9a32008-01-26 14:14:20 +00004025
Georg Brandl3ee81df2008-05-17 18:14:43 +00004026- Issue #1920: "while 0" statements were completely removed by the
4027 compiler, even in the presence of an "else" clause, which is
4028 supposed to be run when the condition is false. Now the compiler
4029 correctly emits bytecode for the "else" suite.
Amaury Forgeot d'Arc31eaafe2008-01-24 22:59:25 +00004030
Guido van Rossumeead05f2008-01-24 18:21:02 +00004031- A few crashers fixed: weakref_in_del.py (issue #1377858);
4032 loosing_dict_ref.py (issue #1303614, test67.py);
4033 borrowed_ref_[34].py (not in tracker).
4034
Vinay Sajipd7cf32e2008-01-24 12:43:33 +00004035- Issue #1069410: The "can't load dll" message box on Windows is
Christian Heimesb2302ba2008-01-23 17:15:06 +00004036 suppressed while an extension is loaded by calling SetErrorMode in
4037 dynload_win.c. The error is still reported properly.
4038
Georg Brandl3ee81df2008-05-17 18:14:43 +00004039- Issue #1915: Python compiles with --enable-unicode=no again. However
Christian Heimes082c9b02008-01-23 14:20:50 +00004040 several extension methods and modules do not work without unicode
4041 support.
4042
Georg Brandl26543b12008-01-21 18:36:51 +00004043- Issue #1882: when compiling code from a string, encoding cookies in the
4044 second line of code were not always recognized correctly.
4045
Georg Brandl14404b62008-01-19 19:27:05 +00004046- Issue #1679: "0x" was taken as a valid integer literal.
4047
Georg Brandl6caad7d2008-01-26 14:19:22 +00004048- Issue #1865: ``bytes`` as an alias for ``str`` and b"" as an alias "" were
Christian Heimes288e89a2008-01-18 18:24:07 +00004049 added.
4050
Christian Heimesc94e2b52008-01-14 04:13:37 +00004051- sys.float_info / PyFloat_GetInfo: The floating point information
4052 object was converted from a dict to a specialized structseq object.
4053
Georg Brandl3ee81df2008-05-17 18:14:43 +00004054- Patch #1816: Added sys.flags structseq. It exposes the status of
4055 most command line arguments and PYTHON* environment variables.
Christian Heimesf31b69f2008-01-14 03:42:48 +00004056
Georg Brandl3ee81df2008-05-17 18:14:43 +00004057- Objects/structseq.c: Implemented new structseq representation. The
4058 patch makes structseqs (e.g. the return value of os.stat) more
4059 readable.
Christian Heimes9c201962008-01-14 03:33:52 +00004060
Georg Brandl3ee81df2008-05-17 18:14:43 +00004061- Patch #1700288: added a type attribute cache that caches method
4062 accesses, resulting in speedups in heavily object-oriented code.
Amaury Forgeot d'Arce4c270c2008-01-14 00:29:41 +00004063
Neal Norwitz3fc15b82008-01-10 05:42:58 +00004064- Bug #1776: __import__() no longer accepts filenames on any platform.
4065 The first parameter to __import__() must be a valid module name.
Christian Heimes3403f152008-01-09 19:56:33 +00004066
Georg Brandlaed6c662008-01-07 17:25:53 +00004067- Patch #1668: renamed THREADDEBUG envvar to PYTHONTHREADDEBUG.
4068
Georg Brandl3ee81df2008-05-17 18:14:43 +00004069- Patch #602345: Add -B command line option, PYTHONDONTWRITEBYTECODE
4070 envvar and sys.dont_write_bytecode attribute. All these can be set
4071 to forbid Python to attempt to write compiled bytecode files.
Georg Brandl2da0fce2008-01-07 17:09:35 +00004072
Georg Brandl3ee81df2008-05-17 18:14:43 +00004073- Improve some exception messages when Windows fails to load an
4074 extension module. Now we get for example '%1 is not a valid Win32
4075 application' instead of 'error code 193'.
Amaury Forgeot d'Arce0b76952008-01-04 02:04:15 +00004076

4080 y) functions.
Christian Heimese2ca4242008-01-03 20:23:15 +00004081
Christian Heimes0a8143f2007-12-18 23:22:54 +00004082- Issue #1635: Platform independent creation and representation of NaN
Georg Brandl3ee81df2008-05-17 18:14:43 +00004083 and INF. float("nan"), float("inf") and float("-inf") now work on
4084 every platform with IEEE 754 semantics.
Christian Heimes0a8143f2007-12-18 23:22:54 +00004085
Georg Brandl3ee81df2008-05-17 18:14:43 +00004086- Compiler now generates simpler and faster code for dictionary
4087 literals. The oparg for BUILD_MAP now indicates an estimated
4088 dictionary size. There is a new opcode, STORE_MAP, for adding
4089 entries to the dictionary.

4101
Nick Coghlanef01d822007-12-03 12:55:17 +00004102- PEP 366: Allow explicit relative imports when executing modules

Georg Brandl3ee81df2008-05-17 18:14:43 +00004118- Patch #1739468: Directories and zipfiles containing a __main__.py
4119 file can now be directly executed by passing their name to the
4120 interpreter. The directory/zipfile is automatically inserted as the
4121 first entry in sys.path.
Nick Coghlan327a39b2007-11-18 11:56:28 +00004122
Georg Brandl3ee81df2008-05-17 18:14:43 +00004123- Issue #1265: Fix a problem with sys.settrace, if the tracing
4124 function uses a generator expression when at the same time the
4125 executed code is closing a paused generator.
Amaury Forgeot d'Arc0d75f092007-11-13 21:54:28 +00004126
Raymond Hettinger1760c8a2007-11-08 02:52:43 +00004127- sets and frozensets now have an isdisjoint() method.
4128
Raymond Hettinger3f8caa32007-10-24 01:28:33 +00004129- optimize the performance of builtin.sum().
4130
Neal Norwitz44f326e2007-10-05 05:29:17 +00004131- Fix warnings found by the new version of the Coverity checker.
4132
Georg Brandl21e99f42010-03-07 15:23:59 +00004133- The enumerate() built-in function is no longer bounded to sequences
Georg Brandl3ee81df2008-05-17 18:14:43 +00004134 smaller than LONG_MAX. Formerly, it raised an OverflowError. Now,
4135 automatically shifts from ints to longs.
Raymond Hettinger8f669372007-10-03 21:18:11 +00004136
Georg Brandl3ee81df2008-05-17 18:14:43 +00004137- Issue #1686386: Tuple's tp_repr did not take into account the
4138 possibility of having a self-referential tuple, which is possible
4139 from C code. Nor did object's tp_str consider that a type's tp_str
4140 could do something that could lead to an inifinite recursion.
4141 Py_ReprEnter() and Py_EnterRecursiveCall(), respectively, fixed the
4142 issues.
Brett Cannon0b14f242007-09-30 19:45:10 +00004143
Georg Brandl3ee81df2008-05-17 18:14:43 +00004144- Issue #1164: It was possible to trigger deadlock when using the
4145 'print' statement to write to a file since the GIL was not released
4146 as needed. Now PyObject_Print() does the right thing along with
4147 various tp_print implementations of the built-in types and those in
4148 the collections module.
Brett Cannon01531592007-09-17 03:28:34 +00004149
Georg Brandl3ee81df2008-05-17 18:14:43 +00004150- Issue #1147: Exceptions were directly allowing string exceptions in
4151 their throw() method even though string exceptions no longer
4152 allowed.
Brett Cannon4c20bc42007-09-11 21:02:28 +00004153
Georg Brandl3ee81df2008-05-17 18:14:43 +00004154- Issue #1096: Prevent a segfault from getting the repr of a very
4155 deeply nested list by using the recursion counter.
Brett Cannona0c05512007-09-10 21:38:27 +00004156
Brett Cannon1e534b52007-09-07 04:18:30 +00004157- Issue #1202533: Fix infinite recursion calls triggered by calls to
Georg Brandl3ee81df2008-05-17 18:14:43 +00004158 PyObject_Call() never calling back out to Python code to trigger
4159 recursion depth updates/checks. Required the creation of a static
4160 RuntimeError instance in case normalizing an exception put the
4161 recursion check value past its limit. Fixes crashers
4162 infinite_rec_(1|2|4|5).py.
Brett Cannon1e534b52007-09-07 04:18:30 +00004163
Georg Brandl3ee81df2008-05-17 18:14:43 +00004164- Patch #1031213: Decode source line in SyntaxErrors back to its

Neal Norwitz0ac60192007-05-27 04:08:54 +00004177- Add new attribute names for function objects. All the func_* become
Georg Brandl3ee81df2008-05-17 18:14:43 +00004178 __*__ attributes. (Some already existed, e.g., __doc__ and
4179 __name__.)
Neal Norwitz0ac60192007-05-27 04:08:54 +00004180
Neal Norwitz8b2bfbc2007-05-23 06:35:32 +00004181- Add -3 option to the interpreter to warn about features that are
4182 deprecated and will be changed/removed in Python 3.0.
4183
Georg Brandl2134e752007-05-21 20:34:16 +00004184- Patch #1686487: you can now pass any mapping after '**' in function
4185 calls.
4186
Collin Winter62903052007-05-18 23:11:24 +00004187- except clauses may now be spelled either "except E, target:" or
Georg Brandl3ee81df2008-05-17 18:14:43 +00004188 "except E as target:". This is to provide forwards compatibility
4189 with Python 3.0.
Collin Winter62903052007-05-18 23:11:24 +00004190
Brett Cannon229cee22007-05-05 01:34:02 +00004191- Deprecate BaseException.message as per PEP 352.
4192
Georg Brandl3ee81df2008-05-17 18:14:43 +00004193- Issue #1303614: don't expose object's __dict__ when the dict is
Georg Brandl21e99f42010-03-07 15:23:59 +00004194 inherited from a built-in base.
Armin Rigo9790a272007-05-02 19:23:31 +00004195
Vinay Sajip8549ce32007-05-06 17:53:37 +00004196- When __slots__ are set to a unicode string, make it work the same as
Neal Norwitzcbd9ee62007-04-14 05:25:50 +00004197 setting a plain string, ie don't expand to single letter identifiers.
4198
Raymond Hettinger13936692007-04-11 18:40:58 +00004199- Request #1191699: Slices can now be pickled.
4200
Raymond Hettinger4db5fe92007-04-12 04:10:00 +00004201- Request #1193128: str.translate() now allows a None argument for
4202 translations that only remove characters without re-mapping the
4203 remaining characters.
4204
Georg Brandl5cb76c12007-03-21 09:00:39 +00004205- Patch #1682205: a TypeError while unpacking an iterable is no longer
4206 masked by a generic one with the message "unpack non-sequence".
4207
Neal Norwitzaa754b72007-03-21 06:39:48 +00004208- Remove unused file Python/fmod.c.
4209
Guido van Rossum143b5642007-03-23 04:58:42 +00004210- Bug #1683368: The object.__init__() and object.__new__() methods are
4211 now stricter in rejecting excess arguments. The only time when
4212 either allows excess arguments is when it is not overridden and the
4213 other one is. For backwards compatibility, when both are
4214 overridden, it is a deprecation warning (for now; maybe a Py3k
Guido van Rossum234b1ff2007-03-23 19:39:01 +00004215 warning later). Also, type.__init__() insists on the same signature
4216 as supported by type.__new__().
Guido van Rossum143b5642007-03-23 04:58:42 +00004217
Georg Brandl3ee81df2008-05-17 18:14:43 +00004218- Patch #1675423: PyComplex_AsCComplex() now tries to convert an
4219 object to complex using its __complex__() method before falling back
4220 to the __float__() method. Therefore, the functions in the cmath
4221 module now can operate on objects that define a __complex__()
4222 method.
Georg Brandl2b869942007-03-17 16:08:45 +00004223
Georg Brandl3ee81df2008-05-17 18:14:43 +00004224- Patch #1623563: allow __class__ assignment for classes with
4225 __slots__. The old and the new class are still required to have the
4226 same slot names.

4232 ``object.__reduce_ex__()`` is called with an object that is faking
4233 its type.

4239
Georg Brandl7b9c5552007-03-12 14:30:05 +00004240- Bug #1678647: write a newline after printing an exception in any
4241 case, even when converting the value to a string failed.
4242
Georg Brandl871f1bc2007-03-12 13:17:36 +00004243- The dir() function has been extended to call the __dir__() method on
Georg Brandl3ee81df2008-05-17 18:14:43 +00004244 its argument, if it exists. If not, it will work like before. This
4245 allows customizing the output of dir() in the presence of a
4246 __getattr__().

Georg Brandl3ee81df2008-05-17 18:14:43 +00004770 the client's request was successfully received, understood, and

4781 (telnetlib, ftplib, smtplib and poplib). This is second part of the
4782 work started with create_connection() and timeout in httplib, and

4784
Vinay Sajip8549ce32007-05-06 17:53:37 +00004785- Patch #1676823: Added create_connection() to socket.py, which may be

Georg Brandl3ee81df2008-05-17 18:14:43 +00004811 AttributeError instead of an IOError when the server's response
4812 didn't contain a valid HTTP status line.

4844
Georg Brandl92a6bae2007-03-13 17:43:32 +00004845- Patch #1603688: ConfigParser.SafeConfigParser now checks values that
Georg Brandl3ee81df2008-05-17 18:14:43 +00004846 are set for invalid interpolation sequences that would lead to
4847 errors on reading back those values.

4903 TestCase and TestSuite subclasses (not instances) are no longer
4904 accepted in TestSuite.addTest(). This should cause no

4906 -- the failure just occurred later, with a more cumbersome
4907 exception.

Georg Brandl3ee81df2008-05-17 18:14:43 +00005296 time so that opening a database previously created with the DB_DUP
5297 or DB_DUPSORT flag set will keep the proper behavior on subsequent
5298 opens. Specifically: dictionary assignment to a DB object will
5299 replace all values for a given key when the database allows
5300 duplicate values. DB users should use DB.put(k, v) when they want
5301 to store duplicates; not DB[k] = v.

5308 characters with ASCII value less than 32. Also, it correctly quotes
5309 dots only if they occur on a single line, as opposed to the previous
5310 behavior of quoting dots if they are the second character of any
5311 line.
